Introduction:
- The CNTN® brand 2P 80A MCB is a high-quality 2-pole miniature circuit breaker that can simultaneously monitor both the live and neutral wires. If one phase experiences an overload or short circuit, our 2P 80A circuit breaker can promptly cut off the power supply, protecting personnel safety.
- Our 2-pole 80A miniature circuit breaker housing is made of high-quality flame-retardant material, ensuring it will not cause a fire under high-temperature conditions.
- Its working principle is very easy to understand: it will automatically cut off the power supply in the event of a short circuit or overload.
- This 80A miniature circuit breaker (MCB) is available in three curve types: B, C, and D. Type B is suitable for home lighting control, Type C is suitable for household refrigerators, freezers, and air conditioners, and Type D can be used for motors.
- If your load is not so heavy, we also can produce 20A 2P MCB.
